Installed 4.3 from 4.2.1 and my CR-10s Pro now keeps trying to go out of bounds luckily I don't trust new software installs so I was standing there when I hit print and watched and ripped the cord out the wall. Downgrading maybe will try 4.3.1 thanks for the awesome software, seriously even with this issue cura is amazing and a downgrade is not unheard of in software.
